ClSTERN-VALVE FOR FLUSHING WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 580,525, dated April13, 1897.

Application filed August 20, 1895. Serial No. 559,883. (No model.)

To all whom it may concern:

Be it known that I, THOMAS H. HUToHIN- SON, a citizen of the UnitedStates, residing at Brooklyn, in the county of Kings and State of NewYork, have invented a new and useful Improvement in Oistern-Valves forFlushing ater-Closets and Ihereby declare that the following is a full,clear, and exact description of the invention, enabling those skilled inthe.

with the siphon-valve, partly in section, in

position.

Letter A represents a tank or cistern of the ordinary type, having aninlet-supply pipe a, controlled by the usual float, the line a: mrepresenting the line of water at the time when the tank is full, and 22 representing the same after a discharge.

B B represent two siphon-tubes of the valve, which are arranged so as toextend to within a short distance of the bottom of the tank.

0 is the stand-pipe of the valve.

D is a semicircularshaped pipe having three openings d d cl, into thecenter one of which the stand-pipe O is threaded, and into the other twothe siphon-pipes B B are threaded. piece, but it is preferably made insections, so that it may be adjustable.

Upon the upper part of the pipeD is avalve K, with valve-plug K upon thelever K. The lever K is attached to the pipe D by means of a pin in thestandard K and has. its ful crum thereon. Upon the end of the levernearest the valve is the balance-ball K while upon the other end thelever is flattened and This whole section may be cast in one This rod isthreaded near its upper vided with a hinged valve E, operated by meansof the chain F lever F, and pull G. The valve is mounted on thecistern-box A, through which its discharge-pipe e passes. It is securedto the box in the usual manner by jam-nuts and washers.

The operation of this device is as follows: The valve E is opened bypulling downward the pull G until a sufficient amount of water hasentered the pipe to operate the siphon. The pull may then be releasedand the water will flow through the pipes B B until the falling of thewater causes the float K to drop, thus opening the valve K by means ofthe lever K and allowing the air to enter and break the siphon.

I have shown the parts of my device throughout as of the ordinaryconstruction used in such articles. It is obvious, however, that otherdetails of construction may be used without affecting the nature of myinvention. I do not claim these particular details. In the constructionof this valve it may be made to operate by using one siphon-tube, butits construction with a plurality of siphon-tubes is preferred, as itworks more promptly when so constructed. WVhile therefore preferringmore than one siphon-tube, I do not confine myself to them.

What I claim, and desire to secure by Letters Patent, is-

In a water-closet cistern the combination of a discharge-pipe providedwith a plurality of siphon legs or branches and a valve for theadmission of air situated at the point where the said siphon-legs meet;said valve being operated by the rise and fall of the water in saidtank.
